While you are not wearing any armor, your Armor Class equals 10 + your Dexterity modifier + your Wisdom modifier. You can use a shield and still gain this benefit.
Your practice of martial arts gives you mastery of combat styles that use unarmed strikes and monk weapons, which are shortswords and any simple melee weapons that don’t have the two-handed or heavy property.
You can spend these points to fuel various ki features. You start knowing three such features: Flurry of Blows, Patient Defense, and Step of the Wind. You learn more ki features as you gain levels in this class.
When you spend a ki point, it is unavailable until you finish a short or long rest, at the end of which you draw all of your expended ki back into yourself. You must spend at least 30 minutes of the rest meditating to regain your ki points.
Some of your ki features require your target to make a saving throw to resist the feature's effects. The saving throw DC is calculated as follows:
Ki save DC = 8 + your proficiency bonus + your Wisdom modifier
Immediately after you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.
You can spend 1 ki point to take the Dodge action as a bonus action on your turn.
You can spend 1 ki point to take the Disengage or Dash action as a bonus action on your turn, and your jump distance is doubled for the turn.
your speed increases by 10 feet while you are not wearing armor or wielding a shield. This bonus increases when you reach certain monk levels, as shown in the Monk table.
At 9th level, you gain the ability to move along vertical surfaces and across liquids on your turn without falling during the move.
